CONCRETE SILO-CI-IUTE.

Specification of Letters Patent. Patented NOV. 11, 1919.

Application filed May 29, 1918. Serial No, 237,228;

1 '0 all whom it may concern.

Be it known that I, BYRON L. CARPENTER, a citizen of the United States, and resident of Newton, in the county of Jasper and State of Iowa, have invented a certain new and useful Concrete silo chute, of which the following is a specification.

The object of my invention is to provide a silo chute of simple, durable and inexpensive construction.

More particularly it is my object to provide a silo chute in combination with a silo preferably provided with a concrete door frame.

A further object is to provide such a silo chute having sections with parts constructed and arranged for convenient attachment to the silo, and for supporting the chute sec tions one above the other.

Still a further object is to provide such a silo chute having means for supporting the chute sections on the silo by bolts or the like which are supported on the hoops on the silo.

With these and other objects in View my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a perspective view of a portion of a silo chute equipped with a sectional concrete chute embodying my invention.

Fig. 2 shows a front elevation of a portion of the door frame of the silo.

Fig, 3 shows a vertical, sectional view through a section of the silo, parts being broken away and shown in section for illustrating the manner of securing the section to the silo.

Fig. 4 shows a perspective View of one of the silo chute sections, showing one of the threaded bolts in modified form to be inserted in position.

Fig. 5 shows a vertical, sectional View through that portion of the chute section which holds the nut.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally a portion of the wall of a circular silo made of concrete blocks or the like having on the outside the vertically spaced hoops 11 and having the sectional door frame members 12.

Extending across one end of each door frame member 12 at one end is. a pair of spaced grooves 13 to receive the threaded bolts hereinafter described. I

My improved silo chute is made of sections the sections being indicated by the reference character 14. These sections have substantially the form of a half cylinder, as shown in Figs. 1 and 4. i

Suitable reinforcing may be placed in the sections, 1

Near each upright edge of each chute section preferably near the middle thereof from the top to bottom, each section is pro vided 011 the outside with a thickened or enlarged portion 15.

In manufacturing the sections a nut 16 is placed in the thickened portion 15 and is connected in the reinforcing 17.

In the mold a screw-threaded bolt or the like is inserted into the mold and into the nut 16, so that the chute section is formed with a screw-threaded opening 18 extending from the nut 16 to the upright edge of the chute section.

Each upright edge of the chute section is formed with a transverse groove 19 just below the opening 18 to receive a hoop 11.

The chute sections are designed to be used with bolts 20. During shipping and storage, the bolts 20 are not assembled with the chute sections, but when the chute sections are installed 011 the silo, bolts 20 are screwed into the openings 18 and the heads are countersunk in the door frame as shown in Fig. 8. They are then preferably covered with cement mortar. The bolts 20 may have nuts 16 and project out from the chute section, as illustrated for instance, in Fig. 3.

The chute sections are placed in front of the door and the bolts 20 are inserted through the adjacent openings 13 and then have nuts 21 placed on their inner ends.

The chute sections are arranged in vertical succession, as shown in Fig. 1, so that one rests upon another.

Any suitable support may be provided for the lower chute section for permitting access to the lower door opening.

It will be noted that the grooves 19 are so arranged that they will receive the-hoops 11 when the hoops are placed at the proper regular intervals, so that the bolts 20 may be supported on hoops 11 for thereby sup- 7 porting the chute sections With less strain upon the other be the case. I

Some changes may be made in the cone struction and arrangement of the various parts of my improved device Without departing from the essential features and purposes of my invention, and it-is my purpose to cover by my claims any modified forms of structure or use of mechanical equivalents Which may be included Within the scope of my claims.

I claim as my invention:

1. In a device of the class described, the combination of a silo having a door frame and having hoops with a sectional chute, each section of the chute comprising a channel-shaped member of plastic material, said sections having in their free edges transverse grooves, arranged to receive said hoops, and having engaging devices extending above said grooves from their free edges parts than Would otherwise Gopiceof this p'atent may be obtained for into the silo structure, and secured thereto so that the engaging devices may be supported by said hoops.

2. In a device of the class described, the combination of a silo having hoops, and having a door frame, with a sectional chute comprising a plurality of sections superposed on each other, each section having the form of a channel and having near its free edges embedded in it a nut, and a passage leading from said nut to the surface of said section, screw-threaded bolts extending through said openings and connected with said nuts, said bolts being extended through said door frame and having locking members on their inner ends, each of said sections having beloW each of said openings a transverse slot to receive a hoop whereby the said bolts may be supported by said hoops.
